Airport Bird Control Methods
Losses to aircrafts due to flying birds might be very common if the birds are not controlled. The losses may even mean the death of passengers on the aircraft. Birds usually fly at low altitudes and are, therefore, very dangerous during landing and taking off of aircrafts. The birds usually affect the flight of the aircrafts by getting caught in some of the crucial parts of the aircraft. The propellers and the engine are the commonly affected parts. When birds are caught up in these parts, they usually cause problems to the way these parts function. Engine failure, overheating, and crashing may be the most common consequences. These results may be dangerous to the lives of the passengers and crew aboard.
Since birds are important in the ecosystem, the methods used in controlling them should not endanger their lives. Poisoning the birds is, therefore, not an option. Different aircraft companies have come up with various techniques to drive away the birds. Electronic sounds, simulated predator attack cries, and alarm calls are some of the efficient and conventional methods used in bird controlling.
Believe it or not, birds and other flying pests are a serious problem for pilots, regardless if they are in a warzone or flying passengers domestically. Birds can get caught in the propellers and engines of aircrafts causing severe problems such loss of engine functions, overheating or crashing that can injure or kill passengers onboard. There many companies, both in the military and commercial airliners spending a lot of money to product aircrafts and passengers alike. There are various methods to minimizing such aerial crisis like bird strikes, there is a growing minority that think shooting or poisons is the best route to take. However, many believe in a more humane way to deal with birds and pests than killing them. Electronic sounds, alarm calls, predator attack cries, ultrasonic waves and sonic sound waves are all of the more preferred methods to discourage birds and other flying pests near runways, but beyond these are much more effective means that have proven reliable.
Bird Control Systems and Products
Bio-Acoustic Sound Systems
These systems cover a small portion of land and are programmed with different sounds adjustable to the customers’ needs and requests. What these systems do is send out a species –specific alarm to warn the animal to not fly in that particular area; predator cries, distress bird calls, or sound harassments are utilized in these systems to ensure birds and pests stay away. Once they hear these sounds the likelihood of them flying near departing or arriving aircrafts are reduced, these sounds discourages them to fly and evidently work since many runways are implementing similar technologies.
Yes, drones is not just a military secret any longer, these devices have found a niche in some public and commercial sectors. Drones have been designed and implemented to discourage and prevent birds and flying pests from impeding the process of aircrafts. It is a remote controlled predator replica equipped with the bio-acoustic sounds previously mentioned. It combines a visually terrifying sight for the birds and a vocalized deterrent is a multisensory attack that leverages birds’ instinctive fears. Drones are commonly used by the military to launch attacks on enemies. The same technology used in drones has been applied in controlling birds from causing damages to aircrafts. A replica of a predator is used to move around the runways to scare away birds. The predator replica is usually controlled remotely by use of some advanced technology. The replica is designed to produce a terrifying sound that will scare away birds that have not seen it yet. The sound produced is same to that produced by bird wailers.
Gas Powered Bird Scare Guns
These are used in wide-open outdoor locations, rural locations mostly like vineyards or orchards. These devices are mounted on a rotary tripod, and offers a full-range of fully-automated programmable systems. These guns spray a liquid petroleum to deter birds and other pests from travelling to a particular area; the drawbacks are these guns spray a irritable stench and only work in a small location which is not suitable for some prospective buyers.
Light and bird lasers chase away birds using a constantly changing light pattern. These intense light patterns are particularly bothersome to birds resulting in them vacating the area to avoid the overstimulation that results from the light show these lasers provide. This is a very effective means to evict aerial pests without harming them, however a drawback to the lasers is it may distract pilots. These lasers can be very bright and can flicker to the owners liking, can you imagine how distracting that could be for someone to trying to land or take off an aircraft? Lasers can be used to prevent birds from getting to certain areas. A light pattern that is constantly changing is very disturbing to the birds. This compels them to vacate the areas with these lights quickly. The method is considered one of the safest methods for the birds. The method is however not friendly to pilots in the aircrafts involved. It can easily distract them from crippling the aircrafts.
Birds just like human beings may become scared when they hear certain sounds. A system that can produce these sounds to vacate a particular area is often installed. The birds are made to perceive that a predator may be present; therefore, they fly away. To ensure these birds are kept away for long enough, the system has to play the sound repeatedly. The sound produced may, however, be unpleasant to other people in the surrounding.
These types of guns were initially used for recreation purpose before a major invention that enabled them to be used in military training. The technology used can also be efficiently used in deterring birds from getting into certain restricted areas. A gun is mounted along the runway; it is filled with liquid petroleum. It is operated by automatic operating programmes. The petroleum liquid is sprayed at a certain range that prevents birds from coming close to this range. This fluid (petroleum), however, produces an irritating smell that may not be favourable to every individual within and beyond the spraying range.
